发布时间:2015-01-18 来源:人大经济论坛
计算机专业论文范文 摘 要:随着网络技术的发展和网络的普及,网络教学已经成为当前的一个教育热点。国家教育部根据当前的教育形式,适时提出了以建设“国家精品课程”为主要内容的“质量工程”,以实现优质教学资源共享,提高高等学校教学质量和人才培养质量。根据教育部的精神,在这3-5年内各大高校共建设了1000多门精品课程。精品课程的建设很大程度上缓解了我国教育上的窘境。 本次设计是围绕《软件工程》精品课程教学网站的设计与实现而展开的。《软件工程》精品课程教学网站是一个典型的基于WEB的网络教学平台,系统以ASP(Active Server Pages)作为开发工具,使用SQL Server 2000作为数据库。经过分析,用户安全性、文件传输、视频教学是该系统的难点。其中本系统的功能主要包括:教学内容管理、作业管理、网上答疑管理、考试管理、资料库管理、公告管理等,这些功能的设计实现使该网站功能完备,易使用,交互性强。 《软件工程》精品课程教学网站为学生提供一个网上自学该课程的环境,为教师提供了一个友好的教学平台,为提高教学质量和教学效益提供一种有效的途径。同时也为国家精品课程的建设添了一份力。 关键词:精品课程 文件传输 教学网站 基于Web Design and Implementation of Teaching Website of Choice Courses for Software Engineering Abstract: Along with the development of networks technology and the popularity of networks, online teaching has already been an educational hotpot. According to the present educational situation, the Ministry of Education, in time, put forward a quality project, which regards building of national choice courses as main content, to share the excellent teaching resources and to promote the teaching quality of colleges and the quality of talents cultivation. According to the spirits of the Ministry of Education, more than 1000 choice courses will be built in 3 or 5 years in colleges. Greatly, the building of choice courses alleviates the educational embarrassment of our country. This project designs and implements a choice courses teaching website of the subject of software engineering. The website is a typical online teaching platform based on the Web. It employs the ASP (Active Server Pages) as developing tool, while utilizing the SQL Server 2000 as database. After analysis, the security of users, transmission of files, video teaching are viewed as the difficulties of the system. And the system mainly includes such functions as management of teaching content, schoolwork management, online replying management, testing management, material management, and bulletins management and so on. The realization of such functions makes the very website a perfect, easy-to-use, high-interactive one. The choice courses teaching website of software engineering provides students with the conveniences of online self-learning, while the teachers with a friendly teaching platform. It is an effective way to boost the teaching quality and efficiency. Meanwhile, it makes great contribution to the building of national choice courses.
